Carolyn MacPhee was 81 when she died on December 31, 2017, in Plano, Texas. Her family initially accepted a natural cause, but they later noticed missing jewelry and unexplained bloodstains in her home, which prompted concern that her death was not natural.

Investigators later linked her death to Billy Chemirmir, a healthcare worker accused of targeting elderly women in the Dallas area. Chemirmir had been in the MacPhee home multiple times in 2016 as a caregiver, and authorities suspect he smothered victims and stole valuables. Her death was one of several that were reclassified from natural causes to homicides after Chemirmir’s arrest in 2018.

Did anyone who knew Carolyn notice visitors or caregiving arrangements in 2016 that could shed light on her case?
